A man who repeatedly insisted he was innocent is now admitting that he fatally shot Allegan County farmer Phil Timmerman nearly two decades ago.Scott Wynne was convicted of murder in 1995 and sentenced to life in prison.He has confessed in a letter to the victim's family and in a recorded interview with police.He says he was angry that Timmerman had leased Wynne family farmland that Wynne considered his. He says he confronted Timmerman in a cornfield and shot him with an assault rifle and a handgun.Wynne says he came clean as a way to apologize.A U.S. District Court overturned Wynne’s conviction in 2003 and ordered a new trial, saying Wynne’s trial was “fundamentally unfair” because a key witness was not allowed to testify. The U.S. Court of Appeals reversed that ruling in 2010 and the U.S. Supreme Court refused to hear the case in 2011.Wynne is in the Lakeland Correctional Facility in Coldwater.
